Description
Original diagnosis after Siverson, Lindgren, Newbrey, Cederström & Cook, 2015 [22014]: Upper and lower anterior teeth markedly enlarged. Most upper and lower lateroposterior teeth with markedly compressed cusp in labiolingual direction. Lingual protuberance of root relatively well demarcated in basal view in both upper and lower anterior teeth but wide and with poorly defined base in lateroposterior teeth. Median indentation of basal edge of root deep and U-shaped in anterior teeth but forming wide and shallow V with rounded apex in lateroposterior teeth. Lingual protuberance of root in anterior teeth broad and dome-shaped in profile view.
